AN AUTHENTICATION-CONVERSION-BASED COMMUNICATION METHOD, SYSTEM AND DEVICE

摘要

An authentication-conversion-based communication method and a gateway device and a system of network edge, the method comprises: acquiring the authentication information of a client device; and encapsulating the authentication information as the external network authentication protocol message, then sending it to the external network in order to execute an authentication of the external network; and applying an external address and allocating an internal address for the client device after the authentication of the external network is succeed; and building a mapping table which denoting the correspondence of the internal address and the external address; and creating an relaying table according to the mapping table and a relaying strategy; and then, making the client device communicate with the external network according to the relaying table. The present invention may make a client access to a gateway and the network operators signed up with the client itself at the same time.
